Application filed August 5, 1911. Serial No. 642,499.

To all whom it may concern:

Be it known that I, AARoN SEGALL, a citizen of the United States ofAmerica, residing at Manhattan, New York city, New York, have inventedcertain new and useful Improvements in Sanitary Bottle-Caps, of whichthe following is a specification.

The drawing is a side view, partly in sec tion, of the upper part of abottle covered by a cap embodying the features of my invention.

In the form shown, my cap consists of a disk 26, adapted to be insertedwithin the neck of a bottle and to close the opening of said neck. Fromthe line of that disk there is an upwardly extending flange,sufliciently long to reach the top of the bottle. The disk 26 and theflange are shown as though made of pieces originally separate, but thatis not necessary. That was done in this instance to convenientlyaccommodate the cap to the form of bottle with a recess in the neck asshown in the drawing. The upwardly extending flange conforms in shape tothe opening in the neck of the bottle and is constructed to fit snuglytherein, the purpose being that it shall fit so as to hold the cap uponthe bottle and to insure that result, I construct it with a sharp angleat the cornor wherethis upwardly extending flange and the part closingthe neck of the bottle come together, as shown at 27. From the top ofthis upwardly extending flange, a-

horizontal flange extends outward to or near the outer line of the lipof the bottle. The presence of such flange prevents any dust fromsettling upon the upper part of the bottle lip and when the cap isremoved the bottle will be entirely clean. From this flange, if desired,a further flange 28 may extend down along the outside of the bottle andfurnish a further grip to hold the cap in place. The result is thatthere is a double holding of the cap to the bottle, sufliciently strongto prevent any extensive displacement. Sometimes I run this outer flangedown sufliciently to extend in under the outer face of the lip of thebottle and in such case, to permit its easy removal, I slit the materialof that flange, as shown at 30. The slits 30 will permit the material ofthe cap to yield sufliciently to allow of its withdrawal and yet, sincethe lower edge is integral, the cap is more durable and less liable tobe torn apart.

The cap is shown as though the disk part 25 and the remainder of the capwere separate pieces; they are however, in fact, substantially integral,having been preferably made of celluloid and fastened together when insuch condition as to result in their permanent cohesion.

As it is sometimes difl'icult to remove this cap, unless special meansto-that end be provided, I have also arranged to curve upward a portionof the cap as shown at 35. This has been accomplished by making twoparallel slits in the upper layer of the part overlying disk 26 andstretching upward the part between the slits to form a curved loop, Thesame result might be obtained in other ways. The loop thus providedperforms another function in that it may yield slightly to permit theupwardly extending flange to seat itself within the neck of the bottle,but being resilient, it nevertheless furnishes a spring brace to holdthat flange in position, thereby giving a better though elastic hold tothe cap than if there were no part 35 raised up between the verticalflange walls. The lip is covered and protected from dust, the cap isheld on with an elastic grip and prevents spilling of the contents andthe depression accommodates a small piece of ice to aid in keeping thecontents, with no danger of the water from the melting of the ice,getting into the bottle, since the cap is sanitary and consequentlynecessarily nonabsorbent.

What ll claim and desire to secure by Letters-Patent, is:

A sanitary cap of non-absorbent. resilient material, adapted for useupon milk bottles,

and comprising a horizontal annular disk, as wide as the top of a milkbottle and adapted to extend to the outer line of the top 'of the bottleto be capped and to the inner line of said top, a downwardly extendingwall in the form of a circular flange projecting vertically downwardfrom the interior line of the horizontal disk portion and conforming inoutline to the circular interior of the bottle neck to which it is to beapplied, and a closing wall extending entirely across the space withinsaid downwardly extending wall, closing said space and aiding in holdingsaid downwardly extending wall in position, with an angle not greaterthan a right angle at the corner where the lower line of the downwardlyextending wall joins the closing wall, some portion of said closing wallbeing ralsed I between the lines of the downwardly exname to thisspecification in the presence of tending wall, from the corner aforesaidtwo subscribing witnesses,' this 1st day of 10 thus constituting aspring holding (ievice, all August, 1911. arranged and combinedsubstantia y as set 5 forth, whereby the cap may be sprung upon AARONSEGALL' the bottle top and held thereon by its own W1tnesses:
